Viral RNA and the Killer Phenomenon of Saccharomyces

  • Chapter
Book cover Genetics and Biotechnology

Part of the book series: The Mycota ((MYCOTA,volume 2))

Abstract

The yeast Saccharomyces cerevisiae harbors two families of dsRNA viruses (L-A and its satellites, and L-BC), two ssRNA replicons (20S RNA and 23S RNA) and at least five retrovirus-like elements (Tyl,..., Ty5), referred to as retro-transposons. Most strains carry all of these elements in spite of the fact that none is known to have a natural extracellular route of infection. This may be a reflection of the fact that Saccharomyces, like many other fungi, mate frequently in nature so that these viruses become widely distributed.
